What does PHMSA expect to see in an ECDA feasibility study?
PHMSA expects an operators IM plan to document a process, and its records to document the implementation of that process, that integrates the information available about the pipeline to demonstrate that its conditions/characteristics are consistent with the operators assumptions. For ECDA, this should include determining the practicality of using two complementary indirect examination tools, assembling information about the pipeline (including coating condition and cathodic protection experience) necessary to define Regions, and identifying areas where indirect tools may not provide accurate readings and determining how those areas will be handled.
